From a philosophy a science is derived; from a
science, an engineering system can be deduced. From engineering come the blueprints, and
the machine-shop directions. And the philosophy of present-day science, summated in
Einstein's relativity, cannot lead to the interstellar cruiser. But another philosophy ¼ ?

- part 3 of
3 -

In the pioneer days of wireless telegraphy the wife of one of the
scientists engaged in developing the new invention was asked by her friends whether she
could explain to them what her husband was doing. "Of course," she said,
"my husband explained it to me just yesterday. Imagine a very long dog. His forelegs
are in Washington when his hindlegs are still in New York. If you pinch this dog in New
York, he will bark in Washington. Wireless telegraphy is exactly the same - but without
dog."

Something similar could be said
about interstellar space-travel. It will be space-travel all right - but without space.
This seems to be a rather asinine statement. Nevertheless, we shall see later on that it
expresses, in a somewhat cryptic fashion, the very secret of a possible space-travel
technique.

We learned in Part 2 of "Achilles and the Tortoise" that neither
Space nor Time are absolute data of our scientific experience, and that they exist only in
an interdependent relation with Matter. But so far we have not yet discussed Matter. Well,
what is Matter? Ancient Greek philosophy had an answer. One of its outstanding
representatives (Democritus) said that Matter is the accumulation of tiny indivisible
particles of an eternal and indestructible substance. All objects and phenomena of Nature
can be explained by quantitative changes in the accumulations and configurations of these
particles. This is the early theory of atoms. It has influenced scientific development for
more than two thousand years. Recently, however, this theory has been modified, and
modified to such an extent that the original idea is hardly recognizable. There are
elementary particles, yes, but - there is something else as well. And, if somebody tells
you that these particles are no particles at all, you won't be able to contradict him.

At first sight the situation looks rather confusing, but this is only due to
the fact that we are momentarily caught in a transition period where we are passing from
Democritus' idea of absolute atoms and absolute Matter to the very novel discovery that
Matter is as relative as Space, Time, color, motion et cetera. Just the same, in order to
find out something about the modern concept of Matter the theory of elementary particles
is still a good starting point. The following table enumerates the particles which were
known to physics up to the year 1953, and also shows, us some of. their properties:

We are rather certain that this table is not exhaustive. According to present
theory there should be an "anti-proton". It is also improbable that the
Meson-group is complete with its eleven members. If the present system of counting
particles is retained, a final table might enumerate twenty-seven or twenty-nine
particles. But this is just a hypothesis.

However, these particles do not have the properties Democritus ascribed to
them. Perhaps the best way to define them is to say, that each particle represents a
"localized" manifestation of a quantum field. Each quantum field, on the other
hand, fills the whole of Space and Time of our present Universe. But there is a difference
between these fields. Only the gravitational and the electromagnetic field are genuine
long-range fields. All the others are extremely short-ranged in their observable effects.
It might be said with a certain modicum of truth that the first two fields represent -
partly at least - the long-range behavior of the short-range quantum fields. The
gravitational and the electromagnetic field are, therefore, called the classical fields.

This abolishes completely the concept of empty Space. It looks as if Space is
physically real only as an extension of the quantum fields beyond the existence of
"solid" matter. This also implies that distance is a quantized property,
produced by gradual accumulation of space-quants.

And what goes for Space should have its analogy in Time. There is no
experimental proof yet, but it is perfectly safe to predict that there is also a smallest
physical unit length of Time, an irreducible time-quant. The concept of the quant, first
discovered to be a property of Matter in its fluid state as energy (Planck), is
undoubtedly the general criterion of whether something is measurable or not. Space, Time
and Matter - as far as they have measurable properties - are quantized. But, as far as
they do not represent an accumulation of quants, they are not measurable. And what is not
measurable does not exist-scientifically speaking. Or does it? Well, the equivalence
between physical existence and measurability is certainly true for classical physics, but
we shall obtain a very different - and most unexpected answer if we couch the available
information in terms of quantum physics.

However, before I attempt to formulate the quantum-physical answer - which,
incidentally, will lead us straight down the road to the problem of space-travel - permit
me to recapitulate the salient features of our problem:

We learn from Cantor's theory of Alephs
that the concept of shorter or longer distances - or interval - is arithmetically
meaningless in the continuum.

We also know from the solution of Zeno's paradox that the phenomenon of motion
is independent of the number of physical - denumerable - space-quants a moving body
transverses. Achilles passes in the same time as many real points, but more space-quants
than the tortoise.

The Michelson-Morley experiment implies that absolute Space and absolute Time
are abstract relations but not physical realities.

The quantum field theory informs us, that the basic substratum of all physical
existence are a limited number of quantum fields, each with the characteristic of
extending over all of Space and through all of Time /1/.

With the help of arguments (1) and (2) the theoretical feasibility of
interstellar and even intergalactic space-travel can be demonstrated. I shall show this by
first analyzing the significance of these arguments. Achilles is capable of traveling,
within the same time, a longer distance than the animal because by doing so he passes no
more and no less real - non-denumerable - points than his competitor. Zeno assumed for the
sake of simplicity that our hero travels exactly twice as far as the animal. But from what
we know about the absolute equivalence of shorter and longer distances in terms of the
transfinite number c [cf. argument (1)] Zeno's point would also be valid if his fast
runner would travel a quintillion times as far as the slow one. The ratio of the distances
is irrelevant. We therefore ask: What makes Achilles overtake the tortoise? The answer is
trivial: He uses longer legs, and by doing so, he compensates for the fact that he has to
pass more space-quants than his opponent.

I'm afraid we should need awfully long legs to step from here to the Andromeda
Nebula. Achilles´ personal method is not very practical for interstellar distances. But
his example demonstrates a general principle. Distance per se does not mean a
thing! The traversing of distance is "purely a matter of operational method"
(Campbell). We have not yet reached the stars, because we use an extremely limited
operational procedure for locomotion - a general procedure, by the way, which includes
everything from the crawling of a toddler to the flight of a jet plane or a rocket.

Our question is: Is there a basically different type of operational method? A
method more adequate to traverse cosmic distances? The answer is Yes, and it is implied by
arguments (3) and (4).

If you have various forms of locomotion, some slower and some faster, but all
unsatisfactory for a certain purpose, you may ask: What is their common characteristic
which makes them all so inadequate? The answer in our case is simple. The toddler, the
tortoise, Achilles or the jet plane, they all try to cover distances by passing
space-quants. But in terms of space-quants there are always shorter and longer distances,
and no matter how good your operational method is, there always comes a point where the
number of space-quants becomes too much for your technique. And viewed from the order of
magnitude of galactic distances there is hardly any difference in speed between the
toddler and the jet. Both are equally outclassed in the race for the stars.

The point, therefore, is, can we envisage an operational method of locomotion
which does not try to cover distances in terms of space-quants? Because as long as we do
so we have to distinguish between shorter and longer distances. Arguments (3) and (4)
suggest that there should be such novel method. Let us find out, therefore, what these
arguments really signify concerning the possibility of interstellar travel. According to
(3) absolute empty Space does not exist in a strict physical sense. Consequently, absolute
distances do not exist either. What does exist is "spatiality" (Einstein) as a
measurable property of matter-in-general, i.e. of all physical states of nature. So the
"absolute" distance between us and, let us say, the Andromeda Nebula, which has
so far made it impossible for us to visit that distant galaxy, is not absolutely real. It
is only relatively real with regard to our toddler-locomotion, and it, would disappear at
once if we were to discover the proper operational technique to deal with such distances.

At this point I imagine I hear some of my readers mutter: "This sounds
fishy! Even apart from the problem of space-flight we know there is a stupendous
remoteness between us and a distant galaxy." Surely, there is! But the point is: Do
we have to interpret it in terms of spatial distance? A trip to the Andromeda Nebula
performed with the velocity of light, would take approximately two million years -
terrestrial time. There is nothing which could prevent our saying: There is a temporal
interval between us and this galaxy. Our space-vessel rests motionless in Space, but a
time interval of two million years will affect the immediate proximity of the Andromeda
galaxy. Motion relative to empty Space is not observable! Motion relative to eventless
Time is not observable either. It follows with inexorable logic that the two statements: I
travel from here to the next, galaxy through Space or - exclusively - through Time are
absolutely equivalent. For, if I travel through Space with the velocity of light, my docks
will slow down to an absolute standstill.

Obviously, Space and Time are interchangeable entities. But they are
interchangeable only on the basis of Matter. When I said, we travel from here to the next
galaxy two million years through Time but not through Space, I measured time outside the
spaceship. When I stated that we travel the same way exclusively through space and not
through Time the latter was measured by the clocks of the ship. The difference between the
two sets of clocks is a material condition! But this means there are three inter-connected
interpretations by which the mutual relations of Earth and Andromeda Nebula may be
defined. We may say:

There is a time interval (T) between the two.

There is a spatial distance (S) between the two.

There is a material gradient (M) between the two.

We discovered that (T) and (S) were interchangeable, provided the material
gradient (M) was represented by a constant. This constant is the velocity of light. It was
assumed that our ship was traveling with that velocity.

In fact, we are quite accustomed to the interchangeability of the three cosmic
components of the Universe in our daily lives! But we never think about it, and we fail,
therefore, to notice the general significance of the most familiar phenomena.

In the preceding article I compared the Michelson-Morley
ether-drift experiment with the situation on two cars traveling on a highway, and I stated
that the difference in results as to the relative velocity of moving objects was due to
the fact that in the case of the two cars there existed an "absolute" constant:
the highway. Now, everybody who has ever driven a car, knows that his locomotion is
subject to the following laws:

In the case of our highway travel (S) is always a constant, let us say, the
distance between New York and Chicago. (S) is basic and cannot be changed. But (T) and (M)
are variable, and to a certain degree interchangeable. We know from our experience that we
can reduce the value of (T) by increasing the value of (M). In plain language: If we spend
more gasoline, rubber, oil et cetera (M) we can save on time (T). But, if we want, to be
economical with our engine, tires and fuel, we must pay for it in terms of longer
duration. There are, of course, practical as well as theoretical limits to this
experiment. Don't forget, not all traffic cops read Astounding, and are ready to accept
our argument that we are only testing space-travel theories as a novel excuse for
speeding.

There is, in fact, a very fundamental limitation to the operational procedure
which affects the interchange between (T) and (M). This classical procedure can never be
good enough to make one of the two components disappear completely, because in this case
the value of the other would become infinite. But just the same, even the primitive level
of terrestrial locomotion permits us to study the basic interchange-relation of (T) and
(M) with (S) being an "absolute" constant.

In the case of the Michelson-Morley experiment the interchange-relation of the
cosmic components is calculated on a different basis. This time the absolute constant is
(M), the material factor, and (M) is represented by the most general property of Matter,
the velocity of electromagnetic waves. Consequently we are entitled to expect in this case
an interchange-relation between (T) and (S). This is indeed confirmed by the
transformation equations of H. A. Lorentz:

and

If we have two systems
K and K´ being in rectilinear uniform motion relative to each other, then the following
relation exists between temporal intervals (T) and spatial distances (S) according to
Einstein's interpretation of the formulas /2/: The faster K
moves relative to K´, the longer will be the time interval transferred from one to the
other system, and the shorter will be the spatial distance in the same transfer. At the
same ratio as time grows, Space tends to disappear. And vice versa. The basis of this
Space-Time interchange-relation is mass or Matter, because at the velocity of light the
increase in mass for any moving body becomes infinite.

So far we have obtained two very important results! If we use spatial distance
(S) as a basis, we obtain an interchange-relation

T « M

(1)

If matter (M) is considered to be the constant we find that

S « T

(2)

holds. Having arrived at this point we can no more evade the question: Is there
a third interchange-relation where (T) is the basic constant? My answer is a very positive
Yes. There must be a third exchange-relation

M « S

(3)

because the mutual interdependence of (S), (M) and (T) is such that the first
two interchange relations could never exist unless a third between (M) and (S) would
balance them. (We shall later demonstrate this in terms of symbolic logic.)

Interchange-relation (3) is the most interesting for us. We know (1) only to
the limited extent of our daily experience in terrestrial travel. (2) Is at the moment a
purely metric problem between the two continua Space and Time. But (3) represents the very
core of modern quantum-mechanical physics. It is becoming more and more difficult nowadays
to draw a distinctive line between what is purely "spatial" and what is
"material" in any physical datum. The borderline between Space and Matter shows
a sharp demarcation in classical physics only. It tends to disappear under the
"boundary" conditions of microphysics as well as of astrophysics. It is only in
the intermediate field of "terrestrial" macrophysics that we seem to know with
some certainty what the difference between empty Space and solid Matter amounts to. In
popular language: It is the difference between something and nothing. Matter is the sum
total of "all things", and empty Space is the total absence of things. Every
child can understand this. But not too long ago a most important formula was discovered:
(Einstein)

E = m×
c2

(4)

(where E = the energy of a body at rest, m = its mass and c = velocity of
light). Since then it has become general knowledge that "solid matter" (mass)
may be transformed into energy (atom bomb), and that it is at least theoretically possible
to re-transform radiant energy (light) into Matter. Does our distinction between Something
and Nothing still hold? Is energy a thing? We are told that Matter is an electromagnetic
phenomenon. But the electromagnetic field extends through all of Space. Space itself
appears to be a field-phenomenon. That means, microphysically speaking, it becomes more
and more impossible to draw a sharp line of demarcation between a thing and the space that
surrounds it.

An analogous intimate relation between Space and Matter exists in macrocosmic
physics. A preliminary remark: Imagine you have a box partly filled with marbles. You take
one after the other of these marbles out of the container till there is nothing left
inside. Nobody will doubt that there is one thing left. That is the empty box. Its
capacity of being a container has not been affected by the removal of the contents. This
idea of the relation between Space and its contents is that of classical macrophysics. But
now let us proceed to macrocosmic physics.

Imagine yourself to be an entity with divine power, and located outside the
Universe. You reach into the Universe and remove from it one galaxy and one nebula after
the other, and you continue to do so till nothing material, not even the smallest
meteorite or the most tenuous wisp of cosmic dust is left in the Universe. According to
common sense two objects should then be left: the empty Space waiting to be filled again
with things, and empty Time waiting for the event of a new creation. Common sense tells us
further that the dimensions of our Universe should not be affected by the removal of
Matter and of events. But common sense has failed us once before when we dealt with
Cantor's theory of transfinite number, and it will fail us again in macrocosmic physics.

We shall throw only a fleeting glance at what happens to Time in a Universe
deprived of all Matter. In our present Universe Time has two directions. It stretches
toward the past as well as toward the future. But in an empty Universe Time would have
only one direction - toward the future. A past would not exist. The possibility of
"passing" Time demands the presence of Matter.

But what about Space? Some time ago the English physicist Sir Arthur Eddington
tried to define the interdependency of Space and Matter in certain equations - in a
somewhat similar way as the Maxwell-Hertz field theory connects the electromagnetic fields
with charges or poles. Eddington´s equations permitted two interpretations which became
known as, the Einstein- and the de Sitter-universe. Einstein's universe is
"static"; de Sitter's is in constant expansion - and contains no Matter!
Consider what that means! A space that "contains no matter" but is in constant
expansion is Matter in some state of radiant energy. It was later discovered (Friedmann,
Lemaitre, Robertson) that Eddington's equations allow of a series of solutions which
define a connection between the extremes of the Einstein- and the de Sitter-universe.

The gist of the theory can be described as follows: If you put some Matter into
the de Sitter-universe, then its gravitational energy will start to counteract the
expansion. The expanding world will start to slow up. If you add more and more material,
you will finally arrive at a point where expansional and gravitational forces balance each
other. This is the static world of Einstein. But if you add even more Matter, then
gravitation becomes stronger than expansion, and the Universe will start to shrink.

It seems as if Matter has a "contracting" effect on Space, and a
corresponding influence on the structure of Time. As far as Space is concerned one of the
ways to describe its relation to Matter is represented by the formula:

As (5) is at present a highly speculative formula I shall not deal in detail
with it. But, even if it is only a rough approximation of the truth, it clearly implies
that distance is a field-effect. By increasing or decreasing this effect spatial distances
can be shortened or made longer. This seems probable anyhow. But distances in our universe
are so enormous that even a considerable reduction of spatial dimensions would not help us
much. What would be the use of pulling a galaxy which is about one billion light-years
away into our immediate "neighborhood" of fifty million parsecs. Moreover, we
would need the energy of millions or billions of galaxies to do it. The very idea is the
height of absurdity.

Fortunately, our basic interchange-relations (1), (2) and (3) suggest something
else. Some way back in these articles I stated that Space and Time are continua; but
Matter has a discontinuous structure it is quantized. Then a very confusing thing
happened: We found out that Space was quantized too, when we traveled through it. Zeno's
paradox was produced by the conflict between denumerable (quantized) and nondenumerable
numbers. How did that happen? The answer is simple: All classical forms of motion demand a
partial "materialization" of Space. We travel through Space by means of a
highway, for instance. And a highway, representing distance, as a functional part of an
act of locomotion, is materialized space. And distance in form of a highway is, of course,
quantized. For the airplane our atmosphere plays the corresponding part. And even the
principle of rocket propulsion - which may suffice for the short hop to, the Moon - is
still based on the idea of quantized motion. It is only a little more sophisticated - you
take your "highway" along with you. This time it is your rocket tubes.

But this convertibility of the spatial continuum into quantized material
existence is only possible if there is a reversed process by which quantized material
distance can be converted into a non-quantized state of continuity. We have at the moment
not yet the slightest idea how this can be managed. Nevertheless we know two things with
absolute certainty. We know that there can be no doubt that this inverse convertibility
from quantized into non-quantized existence does exist. Because our three
interchange-relations,

T « M

S « T

M « S

would not be possible if only: Space could turn up as a
quantized form of Matter, but Matter never as a spatial continuum Matter has spatial
extension in quantized form nobody ever doubted it. Our whole technology is based on that
knowledge. But, if the inverse relation between Matter and Space did not exist we would
have to assume that Matter - and with it Time - would constitute absolute data of nature.
No modern scientist is ready to make this concession.

The other thing we know with equal certainty is that in a technology no longer
based on the discreteness of Matter but on the continuity of Space and Time distance, goes
by the boards. There is no longer any question of shorter or longer distances. They
disappear completely. A line segment one billionth part of a millimeter long is
numerically equivalent to a line segment of any trans-cosmic length.

Only a "little" question is now left. How can we develop a technique
of locomotion which does no more use Space in its quantized material aspect, but which
utilizes Matter in its, non-quantized spatial version? We are fortunate in so far as we
are not totally ignorant in this respect. We have at least some negative knowledge - we
are aware of the data that are missing. First: We shall have to discover the law which
describes the physical interaction between the electromagnetic and the gravitational
field. We need, further, detailed information about the cosmic "glue" that holds
the atomic nucleus together (Meson theory).

One scientist (H. Bethe) has recently expressed the opinion that we need more
powerful mathematical tools to tackle the problem of the nucleus. It may well be that
Cantor's theory of non-denumerable sets will finally provide the answer. It should not be
forgotten that Cantor only discovered the existence of transfinite numbers. How to use
them in physical science is still a mystery to us. In the preceding article I could only
show that non-denumerable sets do apply to the problem of motion in Space, and that their
application demonstrates that distance is a property of quantized Matter but not of a
continuum like Space or Time.

Thus these articles on the problem of interstellar and intergalactic
space-flight would have to conclude on a very unsatisfactory negative note, if it were not
for a recent discovery in the field of applied symbolic logic. We are now well acquainted
with the fact that symbolic logic can be used in analyzing electrical circuits and power
patterns. I shall use this technique in order to demonstrate the basic power pattern all
interstellar spaceships will have to apply. I know, of course, nothing about the details
which will depend entirely on as yet unknown operational procedures of electromagnetic,
graviton, and messianic character, but I know by logical analysis that they will have to
conform to the following structural pattern.

"M," "S" and "T" shall again be the symbols
representing our three cosmic components of the Universe. Their interchange-relation shall
be represented by « ´, « ´´ and
« ´´´ respectively. We then obtain three elementary
principles of interchange:

«
´

«
´´

«
´´´

M

S

T

T

We know, on the other hand, that any physical event involves all three
cosmic components; because, it is physical, and it happens in Space as well as in Time.
That means: No isolated interchange relation of « , « ´, or « ´´ ever happens in the
Universe. We, therefore,introduce two operational procedures:
and
with the intent to combine all three interchange-relations. The choice of these two
procedures is by no means arbitrary. In fact they are the only possible operations, if we
want to combine all three interchange-relations. We shall define
as the combination of the upper line of all three
relations of « ; that means in this case: of M to S, S to T
and T to M.

In order to establish our operational procedures
and
we arrange the cosmic
components M, S and T in all possible combinations in two horizontal lines X and Y. We
then look for the values of in the upper
lines of our « ´, « ´´ and « ´´´ tables, and we always take the second value. Thus, if our
two horizontal lines contain the combination M S or we choose the value S from S M « ´ table. If the combination is
or
we choose again the
second value of the upper line, this time of « ´´.
Accordingly our value must be T, and so on. For
we select the second value of the upper line, this time of the « tables. We thus obtain as definitions of the operations
and
the following table:

X

M M M S S S T T T

Y

M S T M S T M S T

XY

M S M S S T M T T

XY

M M T M S S T S T

This arrangement may seem redundant, to the uninitiated. But it is not. As a
basis for further calculations we need all logically possible combinations, even such
seemingly redundant ones as between M and M, S and S, T and T.

One thing is absolutely certain - no matter how
interstellar and intergalactic space-flight achieved, and what detailed technical
arrangement may be used - all issues space-ships capable of traveling cosmic distances
will have a switchboard based on the two operational patterns of
and
.
The interesting point, of course, is what could be done with it. Well, many things. It is
impossible to predict which of the individual technical procedure that fall into the
pattern of and
will finally be used. This depends entirely on what future discoveries
will be made in nuclear and astrophysics. But we might as well - for the sake of the
practical demonstration of our "switch board" - assume that the description of
interstellar flight, given by one of our outstanding science fiction authors is
approximately correct. Permit me to quote this description from one of Isaac Asimov´s
novels, where one of the officers of a spaceship explains the principles of interstellar
flight to the passengers /4/:

"Ladies and gentlemen! We are ready for our first Jump ¼
The Jump is exactly what the name implies. In the fabric of space-time itself, it is
impossible to travel faster than the speed of light ¼
Therefore one leaves the space-time fabric to enter the little-known realm of hyperspace,
where time and distance have no meaning. It is like traveling across a narrow isthmus to
pass from one ocean to another, rather than remaining at sea and circling a continent to
accomplish the same distance ¼ Great amounts of energy are
required, of course, to enter this 'space within space' as some call it, and a great deal
of ingenious calculation must be made to insure re-entry into ordinary space-time at the
proper point. The result of the expenditure of this energy and intelligence is that
immense distances can be transversed in zero time. It is only the Jump which makes
interstellar travel possible."

Asimov like many other science fiction writers sees quite clearly that the
possibility of space-travel depends on the elimination of spatial distance. We know now
that distance must be interpreted as an accumulation of space-quants, and we travel
distances by passing space-quants. I remarked in Part 2 of this series: No matter how good
our travel methods might become, there is always a critical point where the accumulated
number of space-quants becomes too much for our operational methods. The question,
therefore, is: Will it be possible to devise a technique of locomotion where we
"jump," as Asimov says. In other words:

Where we do not pass space-quants when we cover distance.

We know that what is quantized is the M-factor in the Universe. Neither
Time nor Space, being genuine continua, are quantized per se. It is only their
matter-aspect that gives them a quantized structure. It all boils down to the problem: Can
we get rid of the M-factor in our operations
and . Our highway experience has already
taught us that M and T might be traded against each other - at least to a limited degree.
The same applies to S and T. But if there is general convertibility of all three cosmic
components into each other, it should indeed be possible to eliminate one of the
components operationally. Asimov's description suggests that the M-component should
disappear, because it is the matter-factor that produces distance.

There is a very simple procedure by which the quantized M-factor can be
eliminated. For XY it is expressed by the
formula:

This new series which contains only S and T represents the symbolic meaning of
(6): However, we are more interested in its practical significance for interstellar
travel. Seen from this angle, (6) describes the basic logical pattern of a technical
operation which has ceased to use quantized data. We remember that quantized data are
always represented by M. But (6) does no longer contain an M-factor. (Incidentally, (6)
does not mean that Matter per se has been eliminated, but only its basic feature of
quantization.) It follows that the mathematical theory of (6) is not based on denumerable
arithmetics. Instead, it uses transfinite Cantorian numbers. And we remember that the
concept of distance disappears entirely in transfinite arithmetics. In other words, (6)
describes the energy pattern of a technical operation which eliminates distance.

It can be said with absolute certainty that (6), its corresponding formula for
the inverse operation XY

XY« ´´ XY

(7)

or any other expression of the types (6) and (7) will be the basic formulas of
all future interstellar or even intergalactic space-travel - provided, of course, that our
general assumption of the universal convertibility of Space, Time and Matter is correct.
If it isn't, we might as well say good-by to all our dreams of space-travel outside our
solar system. The distances are too great. The idea of interstellar voyages where space
vessels travel for centuries, and where only the great-grand children of the original
travelers arrive, is perfectly absurd. Interstellar and intergalactic space-travel will
become a reasonable proposition only if we develop a technique which makes distance go by
the boards - entirely. This, however, is absolutely predicated on the assumption of the
primordial interchangeability of the three cosmic components of the Universe, and the
additional assumption that one may be substituted by the other.

There are two components which, are continua, and one which is quantized.
Length of distance or length of interval means nothing in the continuum. It is significant
only for the third (quantized) component. If we are capable of developing a technique
which eliminates the quantized component by substituting non-quantized features, our
problem how to cross the voids of Space is solved. Our formulas (6) and (7) demonstrate
that such a technique is logically possible. What (6) and (7) imply practically can be put
down in very simple words. Everything that exists has three, components. The three natural
components of the Universe are M, S and T. But if Man introduces an artificial state of
existence he likewise needs three components only. But, being artificial, this state of
existence is based on an operation "op" - which, in its turn, acts as a basic
component.

Thus - introducing P for and
- we have now four equally fundamental parameters: P-M-S-T

This adds up to a redundancy, as far as human technique is concerned. We may
omit one of the four components - or rather its properties. If we get rid of P, we have
the Universe just as it is without Man's action. Of, course, P is still there as far as
the objective world is concerned but it is distributed over MST. Process (P) appears in
this case only as a natural event like the falling of rain, lightning, hunger, thirst, et
cetera. But, if we introduce an independent parameter P as a fourth degree of freedom for
action, we add human creative procedure to the natural events - as a means of producing
something which has not existed before. In our special case space-flight But the addition
of P permits us to eliminate the properties of one of the other components by
substitution. Our formulas (6) and (7) did this for the pattern: P-S-T

This is possible because all human technique and action is two-valued. In order
to do something we require operational decisions and two alternative poles to decide
between. Nothing else! Therefore, the pattern PMST is always redundant - as far as any
individual technical procedure is concerned. M (or the properties of M) can be substituted
as well as S,T or P.

However, this redundancy concerns only any practical, i.e., limited,
action or procedure, and not the general rational pattern on which our procedure is based.
That is the reason why we cannot be satisfied that science, as it is known today,
recognizes only three parameters of the Real:

the objective parameter: Matter (M); the dimensional parameter: Space (S); the
relational parameter: Time (T). It is necessary to add a fourth cosmical component: the
operational parameter: Process (P).

As long as we refuse to accept P as an independent parameter we can only build
a technique based on the natural laws inherent in the relations between M, S and T. In
this case we will never reach the stars. The velocity of light as upper limit for the
propagation of physical events in space is such a natural law. And mind you, it will never
be invalidated in a MST-universe. On the other hand, if we add a fourth parameter we gain
a technical dimension in which the laws of a three-parameter-world are not abolished but
capable of - modulation.

I started my "Achilles And The Tortoise" series with an analysis of
the problem of motion, as first conceived by Zeno. Permit me therefore, to conclude this
final installment with a confrontation between the theory of motion in a three- and four
parameter-universe. According to classical principles the phenomenon in question is based
on the formulas. S/M=T, S/T=.M, MT=S. These are expressions of basic laws in a
three-parameter-universe (MST). Of course, P is also present in these three formulas, but
as I remarked before, it is distributed over the other parameters, and, therefore, has no
quotable value as an independent component. This situation is unavoidable, in classical
science.

This science can never provide us with an adequate theory of interstellar
space-flight because the distributed P cannot absorb the quantized character of M. And
nothing can be done about it because, in a MST-universe P can never be taken out of its
distribution. Why not? Well, according to our traditional ideas Matter is Something and
empty Space and eventless Time are Nothing. But what is Process (P)? A very embarrassing
question! It certainly is nothing! But is it a thing? No, we cannot admit that either. The
science we know uses a strictly two-valued logic. In other words, there can be no basic
Third between Something and Nothing. In this system there is no room for an independent P.
Consequently the only method to, find an asylum for the fourth parameter was its
distribution over the other components.

Now we have finally discovered the original source of Zeno's trouble: He could
not define motion because it was neither a thing nor a no-thing. Motion is an event or
process. To put it differently: Zeno's and our analysis of motion showed that this
phenomenon could not be defined in terms of M, S and T. It demonstrated properties beyond
the three-parameter reality of our traditional idea of Nature. We, therefore, introduced a
fourth parameter P. This was done arithmetically by using Cantor's transfinite number c
for the solution of Zeno's Paradox. This provides, us with a new interpretation of
Cantorian transfinite sets. Cantor's Alephs are numbers which do not apply to a
three-parameter-universe. They represent the arithmetical order of the fourth, parameter.
This gives us - this is at least the hope of the present writer - a "satisfactory
correlation of Cantor's ideas with the real universe" (Campbell).

The recognition of Process (P) as a new parameter beside Matter, Space and Time
is equivalent to introducing in experiential terms that so-much-talked-about
"fourth-dimension", through which the first three can be rotated at will. This
method permits the substitution of the properties of one parameter by those of the three
others. The development of a physical science which satisfies these conditions is now only
a question of time. And when this time arrives - "Why, the stars are as near as we
wish them."

/1/ However it should not be forgotten that this concept of
Time refers only to the temporal duration of our present Universe, where T is now
of the approximate order of magnitude of 3× 1017
sec.

/2/ In these
equations v represents the velocity of K relative to K', c is the constant of light, x
indicates the movement along the x-axis, and t represents time.

/3/ A combination
of a « relation of the upper line with one of the lower line
is not possible because it would involve our operational procedures into contradictions.
An example may demonstrate this. If we combine M to S with T to S in one operation we lose
the distinction between M and T, and the « ´´´ relation
becomes nonexistent. Because, if M is changing into S it cannot also change into T within
the same operational procedure. The same holds for T.

/5/ The
transformation effected in (6) is quite elementary. It is done in two steps.
First the interchange-relation to XopY. That means, wherever XopY has the
value M it is changed to S, and where there is a S, it is replaced by M. Then the
procedure op which was originally operative only between X and Y is applied between
the established values of XopY and the interchanged values of (XopY).
